That's six middleweights and two light heavyweights, with Munoz and Boetsch both coming off derailing losses to Weidman and Costa Philippou respectively.

Like UFC 161, there's a strong presence of former Strikeforce fighters on the card as well.

Between the three of them, Gracie, Kennedy and Feijao have 18 Strikeforce bouts on their records, with all three making their UFC debuts in Las Vegas.

Feijao is the lone member of the group not coming off a win, as he most recently had a May 2012 submission win over Mike Kyle overturned to a no-contest decision after testing positive for stanozolol—a banned substance most commonly used for bodybuilding.

Thiago Silva is the fighter most at-risk on the card so far, as the Blackzilian team member hasn't recorded a win since August 2009 at UFC 102. That's due to two failed drug tests, plus a pair of defeats to Rashad Evans and Alexander Gustafsson, giving Silva a mediocre 1-2-0-2 record in his last five trips to the Octagon.
